Ilex plant named ‘BLH01’

ABSTRACT

A new and distinct  Ilex  cultivar named ‘BLH01’ is disclosed, characterized by distinctive low growing, compact habit. Plants are very well suited for performance in the landscape, including as a specimen plant or a hedge. The new cultivar is a  Ilex , suitable for ornamental garden purposes.

Latin name of the genus and species: Ilex hybrida.

Variety denomination: ‘BLH01’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program by the inventor, Robert Edward Lee. The inventor's intention was to develop ornamental Ilex plants with interesting compact plant habits and good landscape performance. This new variety, hereinafter referred to as ‘BLH01’, was discovered as a seedling, resulting from seeds collected form a large open pollination breeding program including many various species of Ilex. Parent varieties and date of the open pollination are unknown. Seeds were planted in Fall of 2005, with selection occurring the following year, and final selection made during 2010. The open pollination, planting and selection of the new variety all occurred at a commercial nursery in Independence, La.

After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘BLH01’ by vegetative cuttings Fall of 2007 at the same commercial nursery in Independence, La. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. At least three generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘BLH01’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BLH01’ These characteristics in combination distinguish ‘BLH01’ as a new and distinct Ilex cultivar:

-   -   1. Unique low growing habit.     -   2. Compact plant.     -   3. Above average resistance to pests and diseases.     -   4. Tolerant of a variety of soils.     -   5. Plants very well suited for landscape use, including hedge         planting or as a specimen.

COMPARISON TO PARENT VARIETY

Parent varieties are unknown.

COMMERCIAL COMPARISON

‘BLH01’ can be compared to the commercial variety Ilex crenata ‘Dwarf Pagoda’, unpatented. Plants of the new cultivar ‘BLH01’ are similar to plants of ‘Dwarf Pagoda’ in most horticultural characteristics, however, plants of the new cultivar ‘BLH01’ differ in the following:

-   -   1. ‘BLH01’ has an outwardly spreading plant habit, plants of         ‘Dwarf Pagoda’ are narrowly upright.     -   2. Foliage of the new variety is small and narrow, foliage of         ‘Dwarf Pagoda’ is smaller and round.

‘BLH01’ can be compared to the commercial variety Ilex crenata ‘Soft Touch’, unpatented. Plants of the new cultivar ‘BLH01’ are similar to plants of ‘Soft Touch’ in most horticultural characteristics, however, plants of the new cultivar ‘BLH01’ differ in the following;

-   -   1. ‘BLH01’ has solid dark green foliage, ‘Soft Touch’ has         foliage with a silver mid-vein.     -   2. Foliage of ‘BLH01’ is strong and firm, foliage of ‘Soft         Touch’ is soft and flexible.     -   3. ‘BLH01’ foliage upper surface is very glossy, surfaces of         ‘Soft Touch’ are matte.     -   4. Foliage shape of the new variety is oblanceolate, foliage         shape of ‘Soft Touch’ is more rounded.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a 2 year old plant of the new variety in a 3 gallon pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
